IMPROVEMENT IN ROLLER-JAW TEMPLE FOR. LOOM.

The Schedule referred t`o in thse Letters Patent and making part o f the same.

and to the letters of reference marked thereon, making.

a part of this specification.

This invention'is an improvement on mypatent, issued September 28, 1869. In that device, it will be seen I make use of two grooved rollers, running together.

My improvement consists in the use of a grooved concaved shell, or a grooved flat shell or surface, in

connection with a grooved roller, or with a toothedl roller, arranged to move laterally on its arbol; I make the teeth of the roller or rollers which run iu the grooves in the shell, or in the grooved flat shell or surface, either plano-concave, lig. 3, or concavo-convex, as seen in g. 5.

For 'heavy woolen cloth, I find the grooved flat shell or surface works much better than a grooved curved shell, as thick, heavy cloth will not yield and render through the curve ofthe shell, but is held securely by the grooved or toothed roller, and the straight gro'oved shell or dat surface.

.When the grooved dat shell'or surface is used, two rollers, side by side, running in the grooves, are better than one, (see g. 6,) and one may be a grooved roller, and the other toothed, or both alike toothed or grooved.

The grooved rollers are mounted on their arbors so that they may vibrate laterally.

The grooved at shell or` surface has bars in front, between and back side of the rolls, and these bars preveut the cloth from going too deep in the grooves. The rollers are mounted on arbors, with room to revolve, and, as heretofore stated, vibrate or slide later. ally thereon, so that the play will allow the cloth to be drawn in between the grooves of the roller and the grooves of the curved shell, or of the grooved flat shell or surface. -Y

As the lay is carried forward, and the cloth slackened, the roller moves outward, and the cloth is drawn through between the grooves by the take-up of the loom; as the lathe moves back, the cloth tightens, and the roller moves inward, which closes the grooves on the cloth, clamping and holding it securely extended widthwise as the reedsileave it. lIhus the grooves are opened and closed with each forward and backward movement of the lathe. The shape of these grooves, and also of theteeth, is new for this purpose; and by reason of such construction, the cloth has more room to pass between and be held bythe edges of the grooves or teeth, which do ,not wedge down on the cloth like the bevel groove, nor do the concavo-convex teeth penetrate the cloth like sharp teeth or spurs.

I construct a swing-stand, for attaching temples to the breast-beam of the loom. This device serves to give motion to the temple, at the forward and backward .movements of the lathe, and at the same time to raise and lower the temple, thus conforming to the motion of the cloth, which is produced by the action ofthe harnesses and the lathe, hereinafter more fully described.

In the accompanying drawings- Figure lis a perspective view of my roller-jaw temple and swing-stand together.

Figure 2 represents the grooved shell H, in the bedpiece of the temple.

Figure 3 represents the grooved roller B.

Figure 5 represents the toothed roller L. v

Figures 6 and 7 represent the Astraight grooved dat shell or surface, and with rollers applied.

Figure 4 represents the swing-stand, detached from the temple.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

It may be made of gray, cast, or malleable iron.

In g. 1, letter A represents the adjustable part of the temple, which is made oval, the inner shrface being hollowed out smooth, with an arbor passing through, as seen at J.

On this arbor is placed thegrooved roller B, or the toothed roller L, having room to revolve, and also move laterally thereon.

Screw h fastens the piece Ato the bed-piece C, and screw c regulates the jaws to the thickness of the cloth.

Letter C, as seen iu figs. l and 2, represents the bedpiece of the temple, in the shell of which, at H, are cut the grooves, which are concaved, and formed so as to clamphthe cloth on the edges ofthe grooves.

Letters e e, on part C, figs. l and 2, represent slots,

for the screws a a. These two screws fasten the tem-I ple to that' part of'v the swing-stand marked I, and it is thereby regulated.

Letter M, in fig. 7, lrepresents the grooved dat shell or surface, and iig. 6, the rollers mounted on 'arbors, running vin connection with the straight grooves. I have shown these rollers with theI caps olf; but caps may be applied, as in the case of the smooth shell in iig. 1. The toothed roller is made by first cutting the concavo-convex grooves, and then cutting transverse grooves, slightly spiral, and reversed on the arbors, so that the teeth bear on the cloth on the convex side. The grooved roller is made as heretofore explained.

The swing-stand fis' made iu two parts, hinged t0- gether, as seen at G. (See igs. l and 4.)

On the part of the stand lettered I E, is cast an ar- THER, OF

bor for a spiral spring, as seen at F. I do not confine y myself to the spiral spring and arbor, as the only means by which the swing-stand may be operated. In some cases, it may be used without any spring. I use the spiral, or its equivalent, or no spring at all.

That part of the stand marked K, consists of two projections, or brackets, between which the spring is placed. These brackets are slightly curved on the upper edges, and admit of opening and closing the stand.

The edge also serves as a stopper, as it comes in contact with flange I, at f f.

The part ofthe stand marked D, has a ilange, with slot d, for fastening the temple and stand to the breastbeam of the loom. I can use my temple by attaching it to the loom in various ways. I do not confine myself' to this swing-stand as the only means of operating my temple; but I do consider this stand `has a more perfect action than any of the other. arrangements in use.'

By attaching the stand to the breast-beam of the loom, with screw-bolt, at slot d, as seen in fig. 1, and regulating the temple for drawing the edgesof the cloth through between the jaws and the grooves, it is ready Afor operating.

As the lathe of the loom strikes that part of the swing-stand marked E, as seen in iigs. 1 and 4, the temple is moved forward, and slightly raised, thus coufrming to the movement of the cloth, produced by the action of the harnesses and the lathe.

Having thus described my temple and swing-stand,

What I claim as my inventionand desire to-secure by Letters Patent, is-

1. A temple, having a grooved shell jaw, in combination with a roller, or rollers, mounted on their arbors to move laterally, and when grooved and toothed, all as and for the purposes described.

2,.l The swing-stand, in combination with temples for looms, when constructed as and for the purposes herein described.
